Video games aren't just about the games, the story or the graphics. Oh, no. Music is so incredibly important. And often, long after you have finished playing, it sticks around, lingers in the back of your brain.

Here are ten songs we sometimes find ourselves either humming or having a hankering for a listen. These are not the best video game tunes, but they are some of the best. There are many more. This is entirely subjective and feel free to add your favorites in the comments!
